tion and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in'multiple unit printing machines, that is, machines employing a plurality of printing mechanismsprinting a plurality of webs. l

In such multiple unit machines, the webs from the units are usually associated andk led to cutting and folding mechanisms for pro-y l ducing the desired products fromthe asso'V It is desirable in this class of ymachines that if one ofthe webs should ciated webs.

break, the remaining printing units in which the webs running through unbroken should be silenced to avoid waste of 'paper while the broken web is being led up to the vfolder to be again associated in proper register with the unbroken webs, and it is desirable to effect this by slowly running the print-4 ing' cylinders vof theunit in which the web is vbroken so that the broken web maybe fed up to the folder.

Itis theobject of the present invention to produce a driving mechanism for such multiple unit machines in which any ofthe units may be run at a slow speed and the vother units silenced, so that a broken web in one of the units may again be brought up to the folder without running the other units, thus avoiding `waste of paper and permitting-a convenient feed of the web to the folder.

f One construction for carrying out the object of the invention is shown in the accompanying drawings, in which Figure 1 is 'a diagrammatic side elevation of a multiple unit printing machine;

speeds, and

Fig. 3 is a detail, partly in section, taken on line 3-'3`ofFig 2.

Referring now to these drawings, the in` vention has been illustrated as used with a multiple rotary printing machine in which there are three printing units, but it will be VINCENT BALL,

-varied in construction.

understood that the invention is capable of use with other types of printing machines, and that it may be used with printing machines having any desired number of units.

In the drawings, these units areindicated generally by the letters A, B, C. Each of these units include the usual printing and perfecting mechanisms forprintingand perfecting the webs W, W and W They particular:` mec anism employed whereby one or more of the units; may be driven to feed the web forward while the vother units are silenced, may `beasomewhat construction illustrated, however, there will In the particular w be provided a common driving shaft 1, f

which is or may be driven from any suitable source of power, as through a train of gearing 2 from a drivenl shaft 8 of the machine, i

this shaft being operated through the usual unnecessary for an understanding ofthe invention. The shaft 1 is what may be called the high speed shaft, through which the printing mechanisms are driven atrunning speed through connections hereinafter referred to.

clutch connection, .not illustrated,as it isy To effect the slow running of any one ofy the units when desired, there is provided a second shaft 4 which may be termed alow speed shaft, which is driven through a suit-r x able train of gearing 5 from a source of power, as a small low speed motor '6. Thel silencing of the units necessary to silence, i

and the running of the unit' desired for drawing the broken web through, is effected from the shafts 1 and 4, through the medium of double clutches, indicated generally vby the numeral 7, one of these clutches being provided for each of the units of the machine, and operating through connections which will nowbe described. v

While'the special construction ofthe driving connections from thel clutches may be g '-varied, these connections will be the same Fig. 2 isa section on an enlargedfscalpartly-broken away, of the'clutch and con-' for all thel units, and it will be necessary to describe but one of them. lReferring now to Fig. 2, and assuming that the construction" therein shown is for driving unit B, the unit isrdriven from a vertical shaft 8 providedv withmiters 9, 10. vThe lower miter 10A `meshes with a miter 11 formed on one end The sleeve 12 has a reduced end 14, to which is keyed, by a key 15, a sliding clutch 16, having engaging members 17, 18 on the opposite faces thereof. High power shaft 1l has fast thereon, beyond the reduced end of the sleeve 14, a stationary clutch member ber 19, thus clutching the sleeve 14 onto the power shaft and driving the unit through the miter gears 11, 10, before referred to.

Now, if a web should break, as indicated at X, in the web W being printed upon by unit B, all the unit-s are stopped by stopping the high power shaft, and the clutch which controls unit B is moved from engagement with the clutch member 19 to engagement with the clutch member 20 on the other side, which isdriven from lthe low speed shaft et, beforevreferred to. The particular means for operating this may be somewhat varied, but as illustrated the clutch member 20 is a gear having engaging .projections or teeth 21 formed on the face thereof,` this clutch member being loosely mounted on the sleeve 12, before referred to, and meshing with a gear 22 on the low speed shaft 4. rilhe drive for the unit when the clutch is in this position, it being remembered that the clutch is keyed to the' Isleeve, is through gear 22,"

vv*tions fromv thelatterto the low speedshaft, y

clutch member 2O,v and sleeve12, through miters '11 and V10, before referred to.

With this construction, the units A, C of the press may remain stationary, andthe unit B may be turned over at a low speed to feed the web through until the broken web W has been properly associa-ted with the other webs lat the folder.
